  5. Heartworm in Canines: Trends in Rhode Island Shelter Populations

    | Contributor(s):: Kelsey L. McKenna

    Each year thousands of dogs in the United States become infected with heartworm, which is caused by Dirofilaria immitis. D. immitis is a parasite that is transmitted to dogs via a bite by an infected mosquito. Nine of the seventy competent mosquito species reside in Rhode Island. The true...

  6. Pinch-induced behavioural inhibition (clipthesia) as a restraint method for cats during veterinary examinations: preliminary results on cat susceptibility and welfare

    | Contributor(s):: Nuti, V., Cantile, C., Gazzano, A., Sighieri, C., Mariti, C.

    Cats are often subjected to minimally painful or forced procedures during routine clinical practice, which can be poorly tolerated, leading veterinary surgeons to need to offer physical restraint, usually aided by an assistant. The aim of this study was to assess the effectiveness and ultimate...

  7. Predictors of cardiovascular events and mortality in the Systolic Hypertension in the Elderly Program pilot project

    | Contributor(s):: Siegel, D., Kuller, L., Lazarus, N. B., Black, D., Feigal, D., Hughes, G., Schoenberger, J. A., Hulley, S. B.

  8. A trained demonstrator has a calming effect on naive horses when crossing a novel surface

    | Contributor(s):: Rorvang, M. V., Ahrendt, L. P., Christensen, J. W.

    Habituated horses have been found to have a calming effect on conspecifics in fear-eliciting situations. In practice, experienced horses are often used as companions when young horses are introduced to potentially frightening situations, like loading onto a trailer. However, studies of social...

  9. The influence of gentle interactions on avoidance distance towards humans, weight gain and physiological parameters in group-housed dairy calves

    | Contributor(s):: Lurzel, S., Munsch, C., Windschnurer, I., Futschik, A., Palme, R., Waiblinger, S.

    The quality of the relationship between cattle and their caretakers is important for animal welfare and productivity. Nevertheless, the influence of gentle interactions on group-housed dairy calves has not been thoroughly studied so far. We examined the effects of 42 min of gentle interactions...

  10. Effects of gentle interactions on the relationship with humans and on stress-related parameters in group-housed calves

    | Contributor(s):: Lurzel, S., Windschnurer, I., Futschik, A., Palme, R., Waiblinger, S.

    Although the relationship between farm animals and humans has strong implications for animal welfare and productivity, there have been few experimental studies on the influence of gentle interactions in group-housed calves. In the present study, Austrian Simmental calves were housed in groups of...

  11. Validating the use of qualitative behavioral assessment as a measure of the welfare of sheep during transport

    | Contributor(s):: Wickham, S. L., Collins, T., Barnes, A. L., Miller, D. W., Beatty, D. T., Stockman, C. A., Blache, D., Wemelsfelder, F., Fleming, P. A.

    We tested the application of qualitative behavioral assessment (QBA) as a welfare assessment tool. Sheep were exposed to road transport treatments, and behavioral expressions were compared between experimental treatments and validated by correlation with physiological measures. We compared...

  12. Horse as significant other: discourses of affect and therapy in Susan Richards's Chosen by a Horse: How a Broken Horse Fixed a Broken Heart

    | Contributor(s):: Nyman, J.

  13. Are results of Crib Opening Test connected with efficacy of training horses in a round-pen?

    | Contributor(s):: Wilk, I., Kedzierski, W., Stachurska, A., Janczarek, I.

    Training the horse is based on human-horse relationship, which requires that the horse shows active, conscious behaviour as well as an ability to learn. It was hypothesized that the horse's learning skill to open the crib is correlated with the effectiveness of training. The aim of the study was...

  14. Effects of sounds of different quality on the behaviour and heart beat parameters of goats

    | Contributor(s):: Johns, J., Patt, A., Hillmann, E.

    In alpine regions, bells are used to relocate free-ranging grazers like cows and goats. Considering that goats have a well-developed hearing capacity, sounds (e.g. a chime of a bell) may act as stressors depending on their characteristics. The aim of this study was to test whether a non-uniform...

  15. Measuring heart rate variability in horses to investigate the autonomic nervous system activity - pros and cons of different methods

    | Contributor(s):: Stucke, D., Ruse, M. G., Lebelt, D.

    Power spectrum analysis of heart rate variability (HRV) may provide insight into the mental state of the animal held in restricted specific experimental conditions. Determining inter-beat-interval (IBI) variations is one way to measure changes in autonomic nervous system (ANS) activity in horses....
